I don't know what the relevance of the actual number of a signal is. Nobody is supposed to use the number, only the macro. But I may be misjudging the situation as a bystander of this discussion.

Furthermore, there is no such thing as "a signal" on Windows (outside of Cygwin), let alone a SIGCHLD. Therefore, this topic about SA_RESTART is irrelevant for the MinGW port.

That said, we have a very stupid emulation of SIGALRM, but it doesn't work like a POSIX signal in any way (if it works at all).
